nation and arrangement of parts and in the The object of the invention is the provision .of an excavator having a dirt elevator mounted in a saidelevator can not only be raised and lowto one side or the other, so that a relatively wide cut (wider than the tractor of the excavator) can be made without running the tractor out the machine also embody of a straight line, ing several improved features of construction to enhance the utility and efficiency thereof.

With the foregoing and view which will appear as the invention resides in the other objects in the description combidetails-of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein the scope of what is claimed without departing from the spirit of the invention.

nism. The various devices are distributed, so that there is no undue strain upon. any partof the shell of the boiler. The boiler l is mounted upon a rear driving axle 2 having the tractor wheels 3 secured thereto,

and the front axle i is connected by a fifth wheel 5 with the shell of the boiler, the, frontor steering wheels 6 being journaled upon A. suitable steering gear 7 is connected to the axle 4 for angling or swinging the same, for purpose of steering, and the steering gear includes a hand Wheel 8 whereby the tractor can be steered as usual.

The tractor carries a steam engine 9 which has its connecting rod 10 connected toa crank wheel 11 keyed upon one end of a transverse shaft 12 journaled for rotation upon the boiler, the operation of the steam engine being controlled in the usual manner. This shaft 12 constitutes the driving shaft.

In order to propel slowly during the operation of the excavat-- ing mechanism, a pair of friction cones l3 aremouuted upon the shaft 12, both of said the, tractor forwardly cones being keyed orm'ade fast to the shaft.

A longitudinal shaft 14 journaled for rotation upon theboiler has a sleeve 15 feathered thereon at that end adjacent the cones 13, and the sleeve 15 carries a rigid friction cone 16 disposed between the cones 13. The sleeve 15 is operated by a lever 17 whereby the cone 16 can'be forced against one or the other of the'cones 13, so as to be properly rotated by the shaft ,12, or the cone 16 lease it from the cones sired to shaft 12.

A gear wheel 18 is secured to the other end of the shaft 1% and meshes with'a gear wheelie?) secured upon the'correspondwith the shaft 14 and carried in any suitable manner by the tractor.

Fromihe pufioy Wheel 65, the cable 63 eX-- tends in and is Wound upon a drum 66 12 mounted upon tho opomtors platform 6? which is s'ecurod upon the boiler. The drum. fiGis opomtiveiy connect-ed with a shaft 68 journaiod uponthe boiler. A sleeve 69 is feathered upon the shaft and carries a friction cone 70 op'posie the cone, 16' and movabie between the cones 13, the sleeve being shifted a Emmi lover '71., whereby 68 om: be connected with the drivsb. 1% 12 some shaft The drum 66 can thus be operated mechani ally for winding up or unwinding, the cable 63 to raise or lower the elevator.

As a means for rotating or turning the pedestal to swing the elevator and its boom 59 to one side or the other, the lower portion of the pedestal is provided with a mutilated worm wheel 72 meshing with a worm secured upon a short shaft 7-1: journaled upon the boiler, and a gear wheel 75 keyed upon the shaft 74: meshes with a smaller gear wheel 76 keyed upon a shaft 77 journaled upon the platform 6'7. Afriction cone i8 is feathered upon the shaft 77' and is disposed between a pair of cones 78 carried by the driving shaft 12, the cone 78 being controlled by a hand lever 79 whereby the cone 78 can be moved into and out of engagement with either cone 78 When the cone 78 is brought into engagement with one cone. 78", the worm 73 is rotated in one direction for turning the pedestal correspondingly, and when the cone 78 is engaged with the other cone '78, the pedestal will be rotated in the opposite direction. Thus by operating the hand lever 79, the pedestal may be turned properly for swinging the elevator through an arc of about 180 degrees.

The excavating mechanismalso includes a conveyor for conveying the dirt discharged from the buckets 42 to one side, and to this end a conveyor frame 80 has one end pivotally engaging a short longitudinal shaft 81 carried by a bracket 89.- attached to the forward end of the boiler shell. A roller 83 is carried by the shaft 81, and a roller 85 is carried by a shaft 84 applied to the 'free end .of the conveyer frame 80. An endless conveyer belt 86 passes around the rollers by means of a sprocket wheel 87 keyed upon the shaft 81 and connected by an endless sprocket chain 88 with a sprocket wheel 89 keyed upon a short horizontal shaft 90 journaled at one side of the boiler, A bevel gear 91 is keyed upon theshaft 90 and meshes with a bevel gear 92 secured to the lower end of a vertical shaft 93 journaled at the side of the boiler. A bevel gear 94 is secured to the upper end of the shaft 93 and 'meshes with a. bevel gear 95 keyed upon The conveyor belt 86 is operated connected by a cable, rod, or the like, 98, to a bail 99 attached to the shaft 84,. A flexible member 100 connects the free end of the boom 96 and the respective side of the boiler, to limit the swinging movement of the boom properly, and the free end of the boom is connected by a block and tackle 101 with the upper end of the pedestal 35 whereby the boom 96 can be raised and lowered for correspondingly adjusting the conveyor. The end of the rope 102 of the block and tackle extends to the platform 67 so that the operator can readily adjust the conveyor.

A hopper 103 is carried by the forward end of the boiler shell below the upper end of the elevator belt, to catch the dirt discharged from the buckets 42, and to direct the dirt onto the inner end of the conveyor, whereby the dirt is carried to one side by the conveyer, to be caught in a wagon at one side of the excavator, or the dirt may. be discharged at one side in a pile or embankment.

The cardinal feature of the invention resides in the peculiar mounting of the elevator, whereby'the elevator can not only be raised and lowered during the excavating operation, but can also be swung .to one side or the other, so that a relatively Wide out can be made without moving the tractor side wise. The cut made is wider than the tractor, so that the tractor can proceed into the cut, and this allows wagons, wheel barrows, or the like, being drawn into the out at one side of the tractor to receive the dirt from the conveyor.

The invention also has other salient features which will be apparent from the foregoing, taken in connection with the drawings.

Having thus described the invention, what is claimed as new is:

An excavating machine embodying a boiler, a steering axle supporting it and:

having ground wheels, a rotatable pedestal 'MARION n. WATTS.
